Passing on an email from The FreeBSD Foundation:
Millions of systems run FreeBSD. Hundreds of volunteers contribute to FreeBSD’s success. But what is the size of FreeBSD’s user base? This simple question is very hard to answer, but its answer is vital to the cause of promoting FreeBSD. It is extremely difficult to convince businesses to invest time and money to add FreeBSD support to their products based solely on vague estimates of the size of our community. We should know - working to make FreeBSD a more widely supported platform is a task the FreeBSD Foundation has worked on since its inception.
Please help us in our fight to promote FreeBSD. A donation to the FreeBSD Foundation helps fund our work, but it also gives us strength in numbers. Our count of unique donors is a vital indication of the size and buying power of our community. However, we have never broken even one thousand donors in any year. We know in our hearts that this is a small fraction of our user base and of those who want to help expand FreeBSD’s presence.
So stand up and be counted! Make a donation. Encourage other FreeBSD users to donate as well. No donation amount is too large or too small. Just by becoming a donor you are making a powerful statement about the strength of FreeBSD!
As the base operating system of this project, much of the work the FreeBSD Foundation sponsors directly benefits pfSense users as well. You can donate here. The FreeBSD Foundation is a non-profit 501(c)3 charity, so your contributions may be tax deductable.
